Here's the 2010 tour dates I've found so far:
March
17 - SXSW - Austin, TX (And I'm guessing they'll do more shows during this festival, right?)
24 - The National - Richmond, VA
26 - Radio City Music Hall - New York, NY
27 - House of Blues - Boston, MA
April
5 - Ogden Theatre - Denver, CO
6 - Ogden Theatre - Denver, CO
13 - Fox Theater - Oakland, CA
It looks like most of these dates are going on sale this week or this weekend. Woohoo!
